ʻO ka PPDI maʻemaʻe 1,4-Phenylene diisocyanate (PPDI), ʻo ka helu CAS he 104-49-4. ʻO ka PPDI kahi mea hoʻomaʻamaʻa kiʻekiʻe / hoʻonui kaulahao no ka polyurethane (PU) thermoplastic elastomers. Hōʻike ʻia nā elastomers casting e pili ana i ka PPDI me ka hana hoʻoikaika maikaʻi. ʻO ka pōmaikaʻi ʻike ʻia ʻo nā huila kiʻekiʻe i hana ʻia me PPDI hiki ke kū i ka wela kiʻekiʻe ma lalo o ka wikiwiki a hoʻomau i ka hana / neʻe. No laila, ʻo nā huila e pili ana i ka PPDI he hopena maikaʻi loa ia no kēlā mau mea e pono ai ke ola lōʻihi, ka mana hoʻouka nui a me nā koi pale wela kiʻekiʻe. Ma keʻano laulā, ʻike ʻia nā elastomers PU me ka abrasion maikaʻi loa, haehae a ʻoki i ke kūʻē ʻana i ka hoʻohālikelike ʻana i nā rubbers synthetic. ʻOiai ʻo PPDI a me MDI he ʻano hoʻohālikelike like, paʻakikī a me nā waiwai modulus i hoʻohālikelike ʻia me TODI, ʻo ka isocyanate ka haʻahaʻa molar ratio o polyol i polyol ma PPDI. ʻO ke kumu, ʻoi aku ka maʻalahi o ka PPDI-type elastomers ma mua o ka MDI-type a me TODI-type polyurethane elastomers. Ma waena o nā polyurethane elastomers, ʻike ʻia nā huila PPDI no nā huila koʻikoʻi loa, ʻo ia hoʻi nā kaʻa no nā forklifts, nā kaʻa a me nā mokulele; nā huila alakaʻi, nā huila no nā mīkini; kiʻekiʻe holo skate rollers a pela aku. I ka pōkole, ʻo PPDI-type elastomer ka koho kūpono no nā noi o ka haʻahaʻa haʻahaʻa a me ke kiʻekiʻe kiʻekiʻe. I kēia mau lā, hoʻohana nui ʻia ʻo PPDI curing agent ma TPU-huahana ma ke ʻano he mea hoʻonui kaulahao nui, a ke hoʻomau nei ka noi ʻana, me nā O-rings, hydraulic seal, coupling stars a me ka pale paʻi squeegee blades.
ʻO nā pōmaikaʻi no kāna mau mea maikaʻi loa o ka wela, abrasion, waimaka a ʻoki ʻia ke kūʻē ʻana, ua hoʻohana nui ʻia nā elastomers e pili ana i ka PPDI ma nā ʻoihana e koi ana i ka deformation paʻakikī, nā hana wela wela. ʻO PPDI ka mea pāʻani nui ma TPU (thermoplastic polyurethane elastomer). ʻO nā sila hydraulic, wipers, piston seals, O-rings, rod sila, pulleys i noi ʻia no ka pale ʻana i ka wela a me ke kūpaʻa ʻana i ke kaomi ʻana he mau mea nui ʻē aʻe o ka PPDI curing agent. ʻAʻole e haʻi i nā kaila no nā forklifts, nā kaʻa, nā mīkini, nā mokulele a me nā pulleys, nā huila, nā alakaʻi wili no nā mea hoʻoheheʻe ʻia ʻo ia ka ʻāpana ʻē aʻe no PPDI-type elastomers.
Hoʻopili: 20kg, 40kg, 50kg / pahu hao.
Ka mālama ʻana a me ka lawe ʻana: He maʻalahi loa ka PPDI i ka makū. Hoʻopili ka wai me nā diisocyanates a pau e hana i nā derivatives urea hiki ʻole ke hoʻoheheʻe. Mai hoʻokomo i ka PPDI me ka meaʻai a pale i ka hōʻike ʻana i kahi kaiapuni ma luna o 30 ℃. Ma hope o ka hoʻohana ʻana, pono e hoʻopaʻa ʻia ka poʻi i ka wā o ka dysfunction. Ma lalo o nā kūlana kūwaho kūpono, kūpono ka PPDI no ʻeono mahina ma ka liʻiliʻi me ka hopena mai ka lā i hoʻopuka ʻia ai.
